Acheulean style artifacts from glacial margin at Licking County, Ohio, ask if there could have been a technological persistence into Late Pleistocene or Holocene new world migrations

Sculpture #5 of 7 from the Buckeye Lake flint sculpture hoard was made using an Acheulean style of large flake removal of selected stone material to make this human head effigy in right profile view, with a bulb of force serving as the ear.

Artifacts at right and left are handaxes found 1/2 mile from the hoard sculpture #5

Reverse sides of the group. Artifact in center is an Acheulean handaxe from northern Africa, made by Homo erectus. It has a typical Sahara desert varnish.

Could there have been an Acheulean related technology persistence into some Late Pleistocene or Holocene new world migrations?  It does not seem likely given current Anthropology- produced archaeological knowledge.

This is a large cordate handaxe made from Black Hand Gorge sandstone, Licking County, Ohio, outcropped bedrock material. Ohio without glacial deposits offers mostly native sandstones, shales, limestones. This material was chosen despite the likely local abundance to the maker of glacial hardstone from Canada, broadly deposited in this area at the terminus of both the Illinoian and Wisconsinin glaciations at 125,000 and 20,000 years respectively. However, it is of suitable weight and with a staggered bit which could have been used in bone breaking to access marrow meats, among many possible handaxe activities.

The handaxe fits ergonomically, perfectly comfortable and workable in the author's hand.
